Here's the doc I found on the SYSTEM_INFO structure: http://msdn.microsoft.com/en-us/library/ms724958(v=VS.85).aspx And here's the doc on GetLogicalProcessorInformation: (spaces added to get through spam filter) http:// msdn.microsoft.com/ en-us/ library/ ms683194.aspx Reading up on it further though,

VbComponents.Remove doesn't always remove module

The particular section I'm looking at is: With ToVBProject.VBComponents .Remove .Item(ModuleName) End With But this VBComponents.Remove call will sometimes only actually take effect once VBA execution has stopped--that is, the delete operation doesn't take effect until all statements are finished, or if the code hits a breakpoint and then I stop debugging. This is a problem because of the following code

Should navigation bars always be implemented as lists?

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: Firstly, very sorry if this is not a "true" stackoverflow question. But it's something I've always wondered about... When you code a navigation bar for a site (html) I've read that it is very good practice, if not the ONLY practice to implement it using the list tag. e.g. <ul> <li> Home </li> <li>About Us</li> <li>Blog</li> <li>Contact Us</li> </ul> And then apply the necessary styling that displays the list horizontally and so on and so forth. But is this standard set in stone or does one only do it this way if it's the best option to do so

Can Kendo Grid be always in edit mode?

We don't want the user to click on a cell or a button to activate the edit mode. We want it the widgets to be displayed and available at all times. Is it possible at all? 回答1: Out of the box, not exactly. You can enable Batch editing which displays everything normally, but clicking a cell will switch it to an editor automatically. Example To enable it, set { batch: true } on the table's datasource. Otherwise you're off to some deeper scripting. Checked and

Deserialization of an array always gives an array of nulls

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I have a custom abstract base class with sub classes that I've made serializable/deseriablizeable with ISerializable. When I do serialization/deserialization of single instances of this class' sub classes, everything works fine. However, when I do an array of them I always end up with an array of nulls on deserialization. Serialization is done with BinaryFormatter. The items are contained within a: public ObservableCollection<Trade> Trades { get; private set; } On serialization this is done in GetObjectData on the SerializationInfo parameter

Will IsConstructedGenericType always be the negation of IsGenericTypeDefinition, for a generic type?

I tried the following code to find the actual behavior of this and related properties: // create list of types to use later in a Dictionary<,> var li = new List < Type >(); // two concrete types: li . Add ( typeof ( int )); li . Add ( typeof ( string )); // the two type parameters from Dictionary<,> li . Add ( typeof ( Dictionary <,>). GetGenericArguments ()[ 0 ]); li . Add ( typeof ( Dictionary <,>). GetGenericArguments ()[ 1 ]); //

Attempting to connect to the instance and transmitting data using an iOS device works flawlessly, but when I try to do it with an android device it fails. I am using the Native java client , and this is the code I'm using on the android side: mManager = new Manager(new URI("https://example.com")); mSocket = mManager.socket("/users"); // socket events listeners mSocket.on(Socket.EVENT_CONNECTING, new Emitter.Listener() { @Override public

Should switch statements always contain a default clause?

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: In one of my first code reviews (a while back), I was told that it's good practice to include a default clause in all switch statements. I recently remembered this advice but can't remember what the justification was. It sounds fairly odd to me now. Is there a sensible reason for always including a default statement? Is this language dependent? I don't remember what language I was using at the time - maybe this applies to some languages and not to others? 回答1: Switch cases should almost always have a default case. Reasons to use a default 1

scipy function always returns a numpy array

匿名 (未验证) 提交于 2019-12-03 08:30:34
可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I'm encountering a scipy function that seems to return a numpy array no matter what's passed to it. In my application I need to be able to pass scalars and lists only, so the only "problem" is that when I pass a scalar to the function an array with one element is returned (when I would expect a scalar). Should I ignore this behaviour, or hack up the function to ensure that when a scalar is passed a scalar is returned? Example code: #! /usr/bin/env python import scipy import scipy.optimize from numpy import cos # This a some function we want

Is C/C++ bool type always guaranteed to be 0 or 1 when typecast'ed to int?

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 由 翻译 强力驱动 问题: Many compilers seem to be keeping only 0 or 1 in bool values, but I'm not sure this will always work: int a = 2 ; bool b = a ; int c = 3 + b ; // 4 or 5? 回答1: Yes: In C++ (§4.5/4): An rvalue of type bool can be converted to an rvalue of type int, with false becoming zero and true becoming one. In C, when a value is converted to _Bool , it becomes 0 or 1 (§6.3.1.2/1): When any scalar value is converted to _Bool, the result is 0 if the value compares equal to 0; otherwise, the result is 1. When converting to int , it's pretty
